问题 Bad eating habits, increased food availability, increasingly sedentary lifestyle and reduced physical activity are the first four causes of the obesity epidemic.
Children who have fat mothers are much more likely to become obese themselves later in life because of ______.
选项
答案genetics and some intrauterine programming
解析 本题涉及到父母肥胖与儿童肥胖的关系，从而将题目出处定位到Prenatal Effects 部分。该部分首段第二、三句提到，在以后的生活中，有着肥胖母亲的孩子更有可能变得肥胖。虽然这主要是由遗传基因引起的．但也有证据表明母亲子宫内的影响对肥胖产生作用，由此可以得出答案。但题干中的 because of要后接名词，所以要再稍加总结。
